Hi Kim
I saw a pain management Dr Brian Delahoussaya from La cruces NM
He did 2 blocks on me and tried me on some different meds,but His firm quit seeing me due to ny skimpy insurance. But He told me and my wife on several occassions that he has cured RSD several times but quote " Biting the head of the snake early". He stated that he had several paitients come in early within a month of contracting it,and his treatment cured them,,,,He sounded sincere ,but he didnt want to do any more shots on me,The first he agreed that he missed,but since the secound didnt work,hesaw no reason to continue,for which i disagreed...either way whether he was lying or not I dont know,,but I think that there are cases that are not too severe without nerve entrapment with other complecations that can be possible cured if found early,,,,,,,,,God bless you,,,,,,,,,bobber
